Gunpowder into a Paste

    Hi everybody ! this is a rare question but what kind of solvent or liquid can I use to make some of my gunpodwer into a paste ?

    I ask because I found a gunpowder that can explode upon impact(quite high impact) so if I find a way to make it a paste I can fill a cup to use as a primer

    I have tried with water and alcohol in a Mortar but have no luck so far...

    BTW the powder its foreign but if anyone wonders its called A-22-C made by FM that its quite fast, designed for the 9mm Luger

    Thanks in advance of any response :)

    I believe the factory solvent for nitrocellulose is alcohol and ether.

    Y'all be careful, now, you hear?

    Try some acetone but please be careful and wear good eye protection.

    I used to make my own primer and bullet sealer with a mixture of acetone and powder. It worked well for that purpose. The powder totally dissolved into the acetone to a smooth consistancy that sealed primer and bullets with less than .0005 thickness. I just imagine more powder would result in a paste but whether or not strong enough for a priming mixture I have no idea. I would be interested in your results.

    Interesting question

    I read through your posting history (just to make sure you were not crazy) and see that you do have a head on your shoulders. I hope this paragraph heads of readers who would make that assumption.

    I did not determine if you have a background in chemistry or not. Trying to find the chemical components of the powder you have might be a good idea, if only to rule out solvents that might produce violent reactions upon mixing. You wouldn't want a facefull of toxic or caustic fumes. Full face shield and good gloves should go without saying.

    All the cautions aside, what do you hope to gain for all this effort? Curiosity? Independence from components manufacturers? Better accuracy? If you use up all your powder in determining how to do this and succeed in your quest, can you get more?

    You might try to find a copy of The Chemistry of Powder & Explosives by Tenny L. Davis.

    Many smokeless powders are based on an ether-alcohol colloid of nitrocellulose (source: Wikipedia), so I might try ether as a solvent to make your paste, but test to see if you have changed the chemical properties of your powder when you get done with it.

    I suspect you will get a lot of criticism for toying with this idea, but I will not disparage you for thinking about it. But without knowing anything else about your goals and experience, my first conclusion is that you suffer from one of two maladies. You have entirely too much time on your hands or you have entirely too much of this powder on your hands.;) Either way, I wish you good fortune.

    I have read that there is a way black powder shooters can make their own percussion caps from aluminum beverage cans and caps from toy guns. I am not sure if that gives you any other ideas, but I though it might pique your interest, so use the information if it does.

    I've actually tried soaking several different powders in acetone before (296, RL22, HS6, and Longshot) to see if they will break down, and they didn't break down at all. But I would imagine not all powders are created the same?
    Just be careful, as already mentioned.

    Paint thinner will work. Mineral spirits.

    I do not think it will work as priming compound, but hey, I could be wrong.

    I saw this McGyver episode 20 years ago that did something similar.....

    priming mixture is different than any paste an inexperienced chemist would be able to make..

    someone with enough expertise to actually do it isn't going to tell you how over the internet..

    Please keep us updated as I would love to up grade my survival weapons from flinters to percussion. [I also want to be secure in your continued survival lol]

    Thanks to every for the replies !

    and specially to Lost Sheep to clarify that im not crazy (for now :p) and give me good info

    I have the basic chemical knowledge of an Industrial engineer meaning basic inorganic chemestry

    I want to get more knowledge about ammunition manufacture because its getting really expensive to shoot here and recently my lazy government directory decided to cut the imports in this country to avoid the economy to hit the bottom of the toilet and most of firearms related products are from USA and Europe, plus the gunstores are stealing us with the prices ,for example a box of el cheapo Wolf primers (SP) are about 10 U$D

    I can get this powder because its produced nowadays ...

    I suffer from both LOL !

    I´ll give a try to paint thinner because alcohol doesn't produce much of solvent proprieties after being in contact for 12 hours

    As far as priming compound, here there is a Factory who sell brass washed steel primers with no paper to avoid humidity to get in the priming mix (the box also says that they are lead free) this primers are the most inexpensive I can buy and it seems that the manufacturer uses gun powder as a priming mix because it has the same colour, heat of explosion and density as the gunpowder A-2 and since the manufacturer its making the huge effort to reduce the inversion at the very least amount of money it might be quite probable

    Ive dissolved smokeless powder in acetone. Turns it into a paste alright. Problem is i doubt ull get the requisite ignition from a pellet of dried paste. The resulting solid block of power burns very slow.

    OTOH if ur powder ignites by percussion it could be a different animal altogether.

    If it's reconstituting primers you're after, there's an easier way. Perchloride is the impact sensitive chemical that composes the white top on a strike-anywhere match. Cut that tip off with a razor blade, smash it into powder, and then CAREFULLY compress it into your disassembled and reconditioned primer cup. Gently press the anvil back in and Viola! Remanufactured primer. They do work, I've used them in 9mm pistols. Each small primer takes about 3 match tips (Large primers will take 4-5), and it is an extrememly time consuming process. IIRC, it too me about 3 hours to "reload" 100 primers, and I had 3 or 4 pop in my face while seating the anvil (not really dangerous, just scares the crap out of you).

    It isn't really a feasible or cost effective thing to do, but it's nice to know you can.

    Where do I get "a Viola"? Midway doesn't seem to carry them.

    the acetone make the gunpowder into a paste in a matter or seconds ! thanks for the data !

    So far I have no luck to turn the paste into a hit and explode mixture ... this propriety is lost when I add the acetone and became a paste but maybe with other quantities I can get what I'm looking for.

    Ill keep you guys updated

    Yep it seems you are right

    I'm sure if match heads can be used for priming compound, a home chemist would be able to come up with a "paste" that could work. Careful of ATF or Homeland Security...
